Problem

A charged particle of mass

m = 1\text{ kg}

and charge

q = 2\,\mu\text{C}

is thrown from horizontal ground at an angle

\theta = 45^\circ

with speed

25\text{ m/s}

. In space, a horizontal electric field

E = 2 \times 10^7\text{ V/m}

exists in the direction of motion. Find the range on horizontal ground of the projectile. Take

g = 10\text{ m/s}^2
